Pesticide Air Monitoring Results Database

Back to Air Program

The Department of Pesticide Regulation maintains a Pesticide Air Monitoring Results Database containing both preliminary and published data from pesticide air monitoring studies conducted throughout California. DPR's Pesticide Air Monitoring Results Database was developed in 2018 to provide access to collected pesticide ambient air monitoring results in an easier to use format.

What's Included?

The database contains both preliminary and published results from seasonal and long-term ambient air monitoring studies conducted by DPR and the California Air Resources Board.

Intensive seasonal ambient monitoring studies are normally conducted in multiple high-use communities during the high-use season for individual pesticides and last anywhere from 4-16 weeks depending on the study. Long-term ambient air monitoring studies are conducted in a single or multiple communities on a year-round basis for one or more years.

Both seasonal and long-term ambient air monitoring studies produce data that is used to estimate concentrations associated with subchronic, annual, and lifetime exposures. Additionally, data collected from these monitoring studies assists DPR in assessing potential health risks, developing measures to mitigate risks, and measuring the effectiveness of regulatory requirements.

DPR's Pesticide Air Monitoring Results Database currently contains air monitoring results from the following studies:

  • Long-Term Ambient Air Monitoring:
    • Air Monitoring Network (2011 – present)
    • Toxic Air Contaminant Program Monitoring (2010 – 2017)
    • 1,3-Dichloropropene Ambient Air Monitoring Study (2016 - present)
  • Intensive Seasonal Ambient Air Monitoring:
    • MITC Monitoring in Fresno County (March – July 2017)
    • MITC Monitoring in Kern County (June – August 2017)

The database is composed of two types of data: Published and Preliminary. ‘Published’ refers to results that have been thoroughly reviewed and verified and have been included in a publication. ‘Preliminary’ refers to newer results that have gone through a preliminary review and verification process, but may be subject to change after further verification, and have yet to be included in a publication.

What's New?

The database contains a total of 49,303 ambient air sample records and was last updated on November 16, 2018
